New Picture-Based quiz could help doctors spot hidden struggles in arm pain patients
NCT ID NCT07031791
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new questionnaire called PETRA that uses pictures to help people with suspected thoracic outlet syndrome describe which daily tasks they avoid because of their symptoms. The questionnaire also asks how often they face those tasks, giving doctors a clearer picture of the real-world impact. The goal is to see if this simple tool can be used routinely in clinics to improve assessment and follow-up.
